摘要:
A method of authenticating a timepiece, such as a watch, comprising at least two procedures. A procedure may comprise analysing vibrations of the timepiece. A procedure may comprise analysing characteristics of a gemstone or gemstones of the timepiece. A procedure may comprise comparing measured or detected characteristics with reference information for the timepiece, and authenticating the timepiece based on the results of the comparison.
摘要:
It is disclosed a stop watch (1) including a time indicator comprising a hand (2), a first scale (31) and a second scale (41). A first part of a time indication is shown by the hand (2) on the first scale (31) and a second part of said time indication is shown by said second scale (41) in combination with said first scale (31). The first scale (31) is fixed and said second scale (41) is movably mounted around said first scale (31). The first part of said time indication corresponds to seconds of a duration counted by said stop watch (1), and the second part of said time indication corresponds to tenths of seconds of said duration.

Timepiece comprising indicator members actuated or not actuated by the movement. These indicator members are composed of movable hour marks represented by the faces of the studs (30, 40) mounted on staffs having planet wheels (34) driven by a rack (50). The faces of the studs carry stones of various colours. When the movement operates the rack, it determines the change of the hour marks. When operation by the movement is disengaged, manual control means allow the hour marks appearing on the dial to be changed.

摘要:
The invention relates to a watch movement comprising an annular casing (10), having an external diameter D, which is provided with a central round opening (48) that is defined by an internal diameter d. According to the invention, the gear train (34) comprises a mobile (36) consisting of a minute wheel (36a) and a pinion (36b), a cannon pinion (38), which is driven by the minute wheel (36a) and intended to support a minute hand (40), and an hour wheel (42) which is driven by the pinion (36b) and intended to support an hour hand (44). The cannon pinion (38) and the hour wheel (42) are concentric to the casing (10) and are provided with a central opening that is more or less equal to d. The minute wheel (36a) is provided with a diameter that is slightly smaller than (D-d)/2.
